Is it possible to download the manual from the Wiki and integrate it into the help menu?
You cannot directly download the blender wiki&hellip; well not as normally as you are asking, there are ways (and even if you did get it, as far as implementing or getting its content into Blender, that's another story).

You can reach the manual from inside Blender however and some documentation functionality is already implemented somewhat..

Hover over a button and you should see a short description etc.. This can be useful for getting operator names.



For more information, right click on the component in Blender and you can choose to go to the Online Manual or the Online Python Reference



You can also just grab a zip of the python reference for offline viewing directly from the front page.
